media-libs/fontconfig: don't enable subpixel rendering by default

This changed in 2.14.2 inadvertently. We have our own mechanism for users
to choose this (eselect-fontconfig) but the default for this option was installing
/etc/fonts/conf.d/10-sub-pixel-none.conf.

Stop doing that and now it installs /etc/fonts/conf.avail/10-no-sub-pixel.conf.

+#   But sometimes it's actually greater than that, e.g. see Fedora's spec file

+# - Purposefully dropped the xml USE flag and libxml2 support. Expat is the
+#   default and used by every distro. See bug #283191.

+# - There's a test-only dep on json-c.
+#   It might become an optional(?) runtime dep in future though. Who knows.
+#   Keep an eye on it.
